Not able to get the lgic of the logic

question: find two non repeeating number using xor

what is the meaning of

int set_bit = XOR & ~(XOR-1);

in https://ide.codingblocks.com/s/344984

#2

hello @aarijrab

this line will give ur righmost set bit of xor.

for example ->
if xor -> 1110
then
set_bit_no = xor & ~(xor-1) = (1110) & ~(1101) = 0010 (note : it is righmost set bit of xor)

#3

will it give the position or the actual value of rightmost set bit…for eg if xor=3…then answer = 1…then what is 1…it is the position of rightmost set bit or what

#4

no it is not position , it is decimal value of binary 0000001
